Automotive relay hi an hnathawh dan azirin chi thum-ah then theih a ni a, chungte chu electromagnetic, solid-state, leh hybrid te an ni. Electromagnetic relay hian electromagnetic coil hmangin contact te khalh turin magnetic field a siam a; structure awlsam tak nei mahse chhanna hun slow (10-30ms vel) an nei thung. Solid-state relay hian contactless switching neih theih nan semiconductor device (MOSFET ang chi) an hmang a, response time chu microsecond level a thleng a, mahse a man a to zawk thung. Hybrid relay hian chi hnih thatna chu a inzawm khawm a, high-frequency switching scenario atan a tha hle.
Automotive control relay hi automotive electronic control system-a thil pawimawh tak a ni a, control system leh controlled system atanga siam a ni. Heng hmanrua te hian electromagnetic induction principle hmangin current te tak te hmangin current lian tak tak an control thin. Motor-a electronic component hman lar ber pawl an nih avangin lirthei hmanrua, headlight, wiper, starter, leh air conditioning system-ah te an hmang nasa hle a, khawvel pumah kum khatah unit tluklehdingawn khat chuang zet an mamawh a ni.
Domestic automotive control relay hi an hmanna lirthei a zirin chi hnih-ah then a ni ber a: pakhat chu European car model-a siam relay a ni a, German leh French technology hmanga lirtheia hman a ni ber a dang chu Japanese car model-a siam relay a ni a, Japanese model-a hman ber a ni.
